MEANS FOR ADJUSTING AND SHORING SHIPS IN DRY SETTING.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed December 29, 1914. Serial No. 879,439.

To all whom it may concern:

Be it known that I, ANDERS FREDRIK WIKING, a subject of the King ofSweden, residing at 141 Folkungagatan, Stockholm, Sweden, have inventednew and useful Improvements in Means for Adjusting and Shoring Ships inDry Setting, of which the following is a specification.

Adjusting and shoring ships in dry setting is a comparativelytime-wasting operation and further not free from danger, especially whenthe docking takes place in turbulent weather or agitated sea. Thepresent invention relates to an apparatus for quickly and safelyaccomplishing this difficult operation.

The apparatus in question is illustrated in the accompanying drawing ina plan view in Figure 1 and in a side view in Fig. 2 while Fig. 3 showsthe same applied to a two sided floating dock. The arrangement, however,can be applied to any two sided dock or slip.

The apparatus is substantially so arranged that the ship hauled into thedock is surrounded on both sides by one or more vertical beams which aremoved simultaneously two and two with the same speed toward the centerof the dock, so that the ship, when being secured between the said pairsof beams, will be shored with its keel right over the center of thedock, and thus the purposes of the apparatus will be accomplishedquickly simultaneously and efficiently. The simultaneous motion of thebeams of each pair with the same speed is accomplished in the followingmanner:

Each beam (for instance the beam 1, Figs. 1, 2) is acted upon by forinstance four shores or braces 2, 3, the outer ends of which bearagainst the beam, while the inner ends of the shores 2 lie in bearings tsecured to the dock side of the inner ends of the shores 8 in bearings 5on a carriage 6 movable along the dock side which here is shown asplane.

When the carriage 6 is moved toward or away from the fixed bearings 4, amovement toward or away from the center line of the dock is communicatedto the beam by the shores 3. The dash and dotted lines in Fig. 1designate the position of the beam and shores in the former case. Themoving of the carriage is effected by means of ropes, screws or in othermanner. In the drawing an arrangement with screws of the followingnature is shown. In collar thrust bearings 8 secured to the dock sidethe one end of two screws 7 is supported, the nuts of which are securedto the carriage 6. The screws are rotated simultaneously and with thesame speed in either direction by means of bevel gears 9 from a shaft15, the carriage 6 being thereby moved and the beam 1, still in verticalposition, moved toward or away from the center line of the dock.

If the shaft 15 is brought into connection with a vertical shaft 11 onthe other side of the dock by means of a bevel gearing 13, anintermediary shaft 10 and a second gearing 14, as shown in Fig. 3, thetwo shafts 15 and 11 can be rotated simultaneously. This latter shaft 11may be provided with bevel gears, screws, a carriage, shores and a beam12 in the same manner as the shaft 15 at the other side of the dock, thebeam 12 then being moved quite uniformly with the beam 1 toward or awayfrom the center line of the dock by the rotation of the shaft 15. 16 arearms in parallelograms which prevent the rotation of the beam 1 aroundits own axis when moving.

The effect of the uniform movements of said beams 1 and 12 toward thecenter line of the dock is illustrated in Fig. 3 by means of a shipwhich has been placed with its keel right over the center line of thekeel blocks and further efficiently supported laterally by the verticalbeams 1 and 12. Of course this squeezing of the ship between thevertical beams should be effected before the keel and block come intocontact with each other, and only after the ship has thus been centeredbetween the walls of the clock the keel and keel block should be broughttogether and the docking be accomplished without interruption.

Having now particularly described the nature of my invention and themanner of its operation, what I claim is:

1. In a dry dock, vertical shoring beams, braces pivotally attachedthereto, certain of said braces being pivotally attached to the walls ofthe dock, carriages slidable parallel to the wall of the dock to whichthe other braces are pivotally attached, and means for sliding saidcarriages whereby the shoring beams may be moved toward or away from thecenter of the dock.

2. In a dry dock, vertical shoring beams arranged on both sides of thedock, braces pivotally attached to said beams, certain of said bracesbeing pivotally attached to the walls of the dock, slidable carriages towhich the other braces are pivotally attached, and means forsimultaneously sliding said carriages thereby moving the beams uniformlytoward the center of the dock to center and shore the ship.

3. In a dry dock, vertical shoring beams arranged on both sides of thedock, braces pivotally attached to said beams, certain of said bracesbeing pivotally attached to the walls of the dock, slidable carriages towhich the other braces are pivotally attached, screws to impart slidingmotion to said carriages, and interconnecting shafts 5 and gears adaptedto rotate said screws simultaneously whereby the centering and shoring0f the ship is efiected in a single operation.

In testimony whereof I have signed my 20 Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,Washington, D. G.
